摘要： A vehicle visibility assist device is started up when a switching operation of a switch for an external vehicle light is detected and when it is determined by a brightness sensor that it is darker outside of the vehicle than a predetermined threshold. The visibility assist device projects infrared light to a region outside the vehicle, captures a reflection of the light, processes an image of the region outside the vehicle, and projects the image onto a surface visible to the vehicle operator.

摘要： A second circuit separately extracts a synchronization signal and brightness signal from an image signal output from a camera for capturing an image of a subject. A gamma amplifier produces a gamma correction signal based on a brightness ratio characteristic in which a display brightness increases as the signal level of the brightness signal increases and the display brightness is set using a display brightness correction ratio which is preferably 70 to 90% of an equi-proportional display brightness correction ratio when the signal level of the brightness signal falls in a high-brightness range. A liquid crystal display receives the gamma correction signal and displays an image captured by the camera with the display brightness set in accordance with the brightness ratio characteristic while synchronizing with a drive timing signal output from a first circuit. Thus, the difference in display brightness between different high-brightness regions or subjects is made large, whereby halation which may otherwise occur between those regions or subjects can be prevented.

摘要： A vehicle night vision support system includes an infrared camera that captures an image ahead of a vehicle; a main display that displays the image captured by the infrared camera; a sub-display; and a control unit that controls the sub-display so as to display warning information when it is determined that there is an object in the image displayed on the main display, and controls the sub-display so as to display the warning information when it is estimated or detected that an object that has disappeared from the displayed image is present in the field of view of a driver.
